Canon EOS 7D AI Servo Test

After owning the 7D for more than a week, I finally get the chance to try out the AI Servo of the 7D... Using the Canon EF 70-200mm f2.8L, I tried to catch some runs by the players of the recent Brunei Softball Tournament...

Setting: Spot AF, centre AF-point, ISO 200, shutter mode - 1/1250 (i forgot to use manual mode)... focusing was concentrated on the wording on his shirt...

and for the pixel-peeper, i also including the 100% crop...

unfortunately, i came to the tournament a bit late and didn't get a chance to try out the outer AF point (yeah, there weren't a lots of running during the last 2 inning)... furthermore, centre AF-point + good lighting condition, i think even the 50D would also do well (even the 5D Mark II might excel in this condition)... will try to shoot some indoor sport or football (that's soccer to you Americans) during the night to further test the AI Servo of 7D...

anyway, as for this test, I think the 7D rock! love the burst! and the AF tracking so far doesn't disappoint me... so i guess, so far, the 7D does stand up to it reputation... cheers...

Carl Zeiss launches Distagon T* 2/35 lens for Canon


A squirrel nimbly scampers along a moss-covered tree trunk. It has made a promising discovery amongst the fallen leaves of an oak tree. A deer emerges from the half darkness of the woods. A photographer documents the winter preparations of various woodland creatures. This requires a versatile, high-speed, easy to use lens that produces razor-sharp images of the details and the entire scenery.

Optical expert Carl Zeiss has now added an EF bayonet to its proven lens for photographic reporting: the Distagon T* 2/35 ZE. The high-speed, moderate wide-angle Distagon T* 2/35 ZE fits all analog and digital EOS cameras. Its classic 35 mm focal length is particularly well-suited for advertising, travel and nature photography as it captures dynamic perspectives with high depth of focus and few distortions.

With a moderate wide angle of 53 degrees (horizontal), the Distagon T* 2/35 ZE can easily capture wide scenery without forcing photographers to consider perspective effects as design elements as they would have to with shorter focal lengths. The relatively short angle of rotation of the precision focusing mechanism enables fast but precise focusing when required.

For the growing number of photographers and videographers using DSLR’s for movie making, the Distagon T* 2/35 ZE is one of four prime lenses making a core set, joining the Distagon T* 2/28 ZE, Planar T* 1.4/50 ZE and Planar T* 1.4/85 ZE. These lenses are well suited for HD video applications due not only to their exceptional image quality, but for the smooth focus and long focus rotations.

The Distagon T* 2/35 ZE features high image quality for the entire aperture and focusing range. Thanks to its sophisticated optical design in which nine lens elements are perfectly aligned, it permits particularly high imaging performance across the entire image field.

When a tripod is not available, the fast f/2 aperture allows easily handling under low light, making perfect pictures possible even under difficult lighting conditions. Thanks to its special optical design and the Zeiss T* anti-reflection coating, this lens captures bright light sources without artifacts. The Distagon T* 2/35 is also perfect on-the-go thanks to its all-metal and extremely durable precision mechanics for which Carl Zeiss lenses are well-known.

This is ZEISS’ fourth wide-angle lens with an EF bayonet (ZE mount). It follows the recent introduction of the two ultra-wide-angle Distagon T* 3.5/18 ZE and Distagon T* 2.8/21 ZE lenses, as well as the moderate wide-angle Distagon T* 2/28 ZE.

The Distagon T* 2/35 ZE will begin shipping on November 16th for a suggested retail price of $870.
